Answer:
Halite
Explanation:
Halite, commonly known as rock salt, is a type of salt, the mineral form of sodium chloride. Halite forms isometric crystals
The correct answer is: introns
Processing of mRNA is process that occurs only in eukaryotic cells. After the transcription, newly formed mRNA molecule is called and it must be processed into a messenger RNA (mRNA). Processing includes:
• Addition of a 5' cap to the beginning of the RNA
• Polyadenilation- addition of a poly-A tail (tail of A nucleotides) to the end of the RNA
• Splicing- removal of introns and linking the exons
After these steps mRNA is mature and used for the further steps (e.g. translation).
Sometimes some genes are alternatively spliced.

What is the function of restriction endonucleases in bacteria?
a) They serve no function.
b)They allow bacteria to genetically recombine with other bacteria.
c) They allow bacteria to engineer new DNA fragments.
d)They provide a defense mechanism against infection by viruses.
Our answer is surely D
d)They provide a defense mechanism against infection by viruses.
Explanation:
Restriction enzyme/restriction endonuclease:
Are produced by bacteria for cleaveing DNA at specific sites. Restriction enzymes cleave foreign DNA in the bacterial cell to fight against infecting organisms.
Pls Note:
Restriction enzyme are used by
bacteria to defend against bacterial viruses called bacteriophages or phages
Answer: Tidaling
Explanation:
It is rise and fall of water in water-seal chamber, used to determine the degree of re expansion of the lungs. It reduction shows the lungs reexpands.
However, with respiratory efforts it is normal.
